Get To Know Crystal Glass

Crystal cup usually refers to a cup or wine glass made of lead-free crystal glass that can be consumed. With the popularization of technology and craftsmanship, crystal glass has been used as a tea cup and has become a favorite of fashionable people in the new era; Another type is the common crystal wine glass. Lead free crystals are highly favored by consumers and processing manufacturers due to their higher transparency and brightness. Firstly, crystal cups are also a type of glass cup, and their main component is silicon dioxide, with the addition of substances such as lead, barium, zinc, and titanium. Due to its high transparency and refractive index, this type of glass has a smooth and crystal clear appearance, hence it is called crystal glass. If lead is introduced, it is lead crystal. If substances such as barium, zinc, titanium are introduced, it is lead-free crystal. How to distinguish between the two? Just by the touch. Due to the stronger thermal conductivity of crystal compared to glass, touching crystal with hands should be cooler than touching glass. Take a closer look at the hardness. The hardness of natural crystal is 7, and the hardness of glass is 5, so crystal can carve glass. Check the refractive index three times. Raise a crystal cup and rotate it towards the light, and you will find that it is like an exquisite handicraft, pure white, transparent, reflecting charming colorful light. Because crystals can absorb luster, even ultraviolet rays, ordinary glassware has no luster, let alone refraction. Listen to four voices. Gently tapping or flicking the container with your fingers, Crystal Glassware can produce a crisp metallic sound and a beautiful lingering sound in the air, while ordinary glassware only emits a muffled "click, click" sound.

Production process and characteristics. The crystal cup body is made of high-grade crystal glass and carefully processed and fired with superb skills. It adopts a high-temperature firing process of 640 ℃ to reach the critical point of crystal glass melting, which is transparent, pure and non-toxic. At the same time, annealing process is used to ensure that the cup body can withstand the instantaneous changes of heat and cold, explosion-proof and crack proof, no tail vacuum, and has the characteristics of high transparency, strong crystal feeling, wear resistance, etc. It is crystal clear, elegant and generous. At the same time, the double-layer glass structure has a certain cold and heat insulation effect; The cup mouth is polished smooth by special technology, providing a comfortable taste when consumed; More convenient to use, more reasonable in design, and more user-friendly. Advantages of crystal cups: As an important member of cup products, crystal cup products have gradually shown their advantages in drinking water. The advantages of crystal cup products include: the surface of crystal glass material is smooth, easy to clean, healthy and hygienic, while stainless steel cups, purple clay cups, etc. have gaps on their surfaces that cannot be observed by the naked eye. Bacteria, impurities, tea stains, etc. are easily attached and difficult to clean; Crystal cups are transparent and pure, allowing you to see the shape and color of the brewed tea and other beverages, providing a pleasant sensory experience; Crystal cups have a certain cooling and heating effect, and have the best tea brewing effect, ensuring good taste and repeated brewing of tea. The vacuum structure of stainless steel cups can easily cause tea leaves to become sticky during brewing, affecting the taste; The colorful patterns on the crystal cup are varied and finely crafted, complementing the drink in the cup and reflecting the user's taste; High end crystal Glass Cups, with their handmade craftsmanship and exquisite packaging, have become excellent gifts and collectibles.
